According to Pew Research Christians remained the largest religious group in the world in 2015, making up nearly a third (31%) of Earth’s 7.3 billion people. But the number of Christians in Europe, is in decline.
But among Christians in Europe deaths outnumbered births by nearly 6 million from 2010 to 2015. In Germany alone, there were an estimated 1.4 million more Christian deaths than births.
Demographics is destiny. Unless you start winning Europeans who are far from God.
